In fact, to stay healthy, hermit crabs need to eat just like we do if we are maintaining a nutritional diet.  Simply put, hermit crabs are omnivores, just like we are.  They can eat meats, they can have fish, they can certainly have vegetables, and you can even give them fresh fruit for dessert.  Whenever possible, these foods should be organic, or at least unprocessed.  Everything needs to be washed thoroughly before being served.  After that, especially with vegetables and fruits, let the food dry.  Hermit crabs also eat foods rich in tannin.  This includes oak tree leaves and even bark.  These too need to be washed and left to dry. humans eat them
